Growing Orchids Made Easy!

By Michelle Salter

Orchids once had the reputation of being rare and expensive; beautiful, exotic plants that required plenty of attention. Previously this may have been true, but now, with more than 100,000 man-made hybrids to choose from, orchids are readily available and have become popular houseplants.

There are two basic types of orchids. Terrestrial orchids grow at ground level and are rooted in soil. Epiphytic orchids grow on trees and shrubs, but are not parasitic, using their host's branches purely for support. The thick, fleshy roots of epiphytic orchids absorb moisture and nutrients from the air around them.

Indoor orchids are generally epiphytic, as they enjoy warm conditions and tend to have more flamboyant flowers than terrestrial orchids. Phalaenopsis, known as Moth Orchids, are one of the most widely available orchids, with displays of pink and white varieties to be found in most garden centres and supermarkets.

Although Phalaenopsis are epiphytic, they can be grown in clear pots. They need a warm environment and providing their roots remain moist and pliable, they will carry on producing flowers for up to 3 months.

Terrestrial orchids are mainly herbaceous perennials, native to temperate regions of the world, and generally hardier than epiphytes. Some terrestrial orchids can be grown in cold greenhouses or even in gardens where the temperature doesn't fall too low in winter.

The flowers of terrestrial orchids may not be as showy as epiphytic types, but they are just as stunning. Paphiopedilum, known as Slipper Orchids because of the distinctive pouch-shaped lip at the front of the flower, were once the most fashionable indoor orchid, before the advent of central heating allowed Moth Orchids to thrive.

Slipper Orchids provide an unusual alternative to Moth Orchids, with broad, dark green leaves and long upright shoots of flowers, which can be spotted, striped and sometimes hairy. They are just as easy to look after as Moth Orchids, and their exotic flowers last just as long. Although terrestrial, they require the same loose compost as epiphytes.

When it comes to caring for these attractive houseplants, there are a few general rules that apply. Avoid direct sunlight, which will damage the plant, and use a specialist, open structured compost that won't become compacted and allows good drainage.

Orchid Tips - The Fall Season is Here


by Rob Roy

The fall season for orchids is an important one. It is one where a great number of the orchid plants need care as well as the change in the basic requirements. Most orchids use this season as a "rest period" to get ready to produce blooms in the winter or spring.

From the summer season to the fall there is a less a requirement for water as the temperature decreases. You will need to monitor this closely. Don't forget it you see wrinkling on the leaves this means that you need more H2O.

As a general rule this time of the year requires the use of an orchid fertilizer richer in phosphorous is needed to boost the bloom potential. This means that there is higher percentage in nitrogen-phosphorous-potassium in the fertilizer mixture. As you use fertilizer on the orchid plants use it as half strength and generally once a week.

I like to fertilizer after I have watered the plant. Once again be sure that you allow the water and fertilizer to run out of the pot. Leaving water and fertilizer in the pot allows root rot to destroy the orchid - very quickly.

The temperature is also getting cooler in most parts of the country during the fall. So if you have plants outdoors you may start to think about getting them indoors. Most orchids can do well in with temps in the 50's and few do ok into the forties. I like to suggest that your plants come inside when the night temps are in the mid fifties.

Now let's get to some specifics for some of the different genera. For cattleyas there growth rate will tend to slow as the fall progresses. The sheaths on the catts will show some changes indicative of blooming over the next six months. Don't forget the fertilizer and watering. These plants do well in bright lighting.

Also, if you are bringing your orchid indoors from being outside check carefully for any pests that may be clinging to the plant. Cymbidiums may start blooming in the fall and they need to be in shaded cool areas. Cyms have a genetically based warmth tolerance but for the best blooms they need an area that is shaded and somewhat cooler. The spikes with the flowers, called inflorescence, needs to be staked to prevent the heavy flowers from weighting down the spike.

Phalaenopsis are just starting to go through the next stage to ready for blooms in the late winter and spring. They need the cool difference in daytime and nighttime temps. It is recommended that there be about a 10 - 15 degree Fahrenheit difference. Phalaenopsis also need to be watered and fertilized less often during this first few months of fall. They are resting. It would helpful to give them a fertilizer with a higher phosphorous percentage to help boost the blossom potential. This fertilizer is also called "blossom booster".

Dendrobiums also need a "blossom booster" as well at this time of the year. Remember their flowers are usually plentiful and grow toward the top of the spike making them top heavy. Use a stake to help hold them erect and be sure that the pot is heavy enough to keep itself upright.

The green leaved Paphs are also getting ready to have flowers. The shafts are displaying the spikes. Be careful with these orchids as a sudden heat spell will prove disasterous to the new blooms. Keep them in a cooler area and with good air circulation.

Paphs don't like to get dry so be careful with watering. If you were watering twice a week try cutting down to once. But while doing this test your medium with the dry tip of a pencil. Stick it down about an inch or two into the pot, if the tip comes out wet your fine.

This should help you to have great orchids both in the fall season and beyond.

Why Are My Orchid Leaves Turning Yellow?

by Rob Roy

This month I want to talk about yellowing orchid leaves. There are many reasons why leaves turn yellow. This is a common question that we receive. Orchids like all other plants age and during that aging process the older leaves will turn yellow and die. Remember we are saying the older leaves of the orchid plant, those toward the bottom.

Let's turn our attention to leaves that are not old and not on the bottom of the plant but newer leaves on the orchid. Some of the other reasons include: 1. Bacterial or fungal disease 2. Too much light 3. Too much water 4. Enviormental

Bacterial or fungal disease on orchid leaves will show itself as irregular yellow spots on the leaf. In other words it will not involve the whole leaf but just spots on the orchid leaf. If there is a black growing edge to the yellow spotting then this is caused by a fungus.

The treatment for the bacterial infection is with Physan which can be purchased at a nursery. For the fungal infection a fungicide for plants or orchids will do fine.

Yes, yellow leaves on orchid plants can be due to too much light. In fact, in the mid day summer sun orchids can actually get burned spots on their leaves. This may be one of the more common reasons for yellowing of leaves.

Place the plant in indirect bright light for a while and it will recover just fine. The leaves will remain yellowed and will not turn back to green.

Although, not usual, too much water can will also cause the leaves to turn yellow. But in addition there will be evidence of "rot" as well. Too much watering can cause a fungal infection and this is seen with black areas within the yellow area as seen in this picture.

Stop watering for a week or two and then only once a week after. You need to treat for a fungal infection.

What sort of enviormental issues cause yellowing of orchid leaves? The biggest is cold weather. Yes, when orchids are sbject to cold weather their leaves can turn yellow due to the damage caused. This can affect the whole leave(s) or parts of them.

Also, certain enviormental toxins can create this condition such as paint fumes or cleaning fumes. When these are being used be sure to get air circulation moving around the orchids.

As you can see there are quite a few causes of yellowing leaves. Treat the easy ones first unless you suspect a more serious problem like a fungal or bactierial infection. If you have questions consult a good nursery or your local orchid society.

Orchid Care by Clark Covington

Any flower or plant will require a good amount of looking after, none more so then the orchid. The orchid is a tender flower that must be carefully looked after for maximum growth potential. The orchid must be planted correctly, with the right feed, the lights must be correct, and temps must also be accurate. After all that you must know when and how to water the orchid. All of this is worth it for the simple beauty an Orchid can provide.
Low light is necessary for certain orchids to grown and mature. The orchids that will need low light are called warm weather orchids. Typically they should be put in a place in the house that isn't too sunny. Warm weather orchids are usually the Paphiopedilum or Lady Slipper, Phananelposis, and the Oncidium. These orchids should be behind the curtains, blinds, or even in a corner of the house. The leaves of the orchid should be a bright green color, if the color is different it probably means the orchid is getting either too much, or not enough light.
Another set of Orchids need larger amounts of light, these orchids are called high light orchids. The high light orchids are ones that grow best with plenty of sun light, so you most likely want to place them in direct view of the sun in your house. The high light orchids are also healthy when they have the vivid green color leaves, if the color is off it probably means they need more light. The high light orchids are called the Cattleya, Dendrobium, and Vanda.
Temperatures must fluctuate for each type of orchid in order for it to stay healthy. Static temperatures, like you would find in an incubator will hurt, and eventually kill orchids. Temperatures should range from 80 degrees during the day, to as low as 55 degrees during the evening hours. In order for the orchid to bloom it needs to store carbohydrate energy during the day, to survive the cold nights. If it is able to do this it will blossom into a robust flower full of color.
Make sure to water the orchids early in the day so they are able to dry out by night. Orchids are tender flowers when it comes to watering and must be treated carefully in order to achieve the best results possible. Orchids should be watered as early in the morning as possible to gain the best chance for dry out by evening.
The type of water used with orchids is extremely important. Orchids are best fit for rain water, because tap water typically has chemicals in it such as chlorine. Rain water will help the orchids reach its full growth potential each day, without compromising its colors, and natural beauty.
